What is the best way aside from shutting lights off for a week to get rid of the green hair alge. I have a terrible outbreak and its driving me nuts!! I have even considered just getting rid of the probmatic rock, becuase it has come back a couple times now. Any help would be greatly appreciated. fyi tank is a 55 with just 1 400 w 20k MH...runs for about 10 hrs before the problem............ has been running good for about two years, but over that last few months this stuff has gotten out of control........thanks...:mad2:

I had a real bad case of GHA too. I scrubbed the rock and basicly kept removing it from the rocks until it finally went away. I strill have a couple of patches I could'nt reach.
I'm also running a fuge with Chaeto....

your best bet is to take it out and scrub it with a toothbrush really really well. It shouldn't come back after that. Trust me thats the ONLY way. I've been there.

i changed out of date lights and did a big water change and mine was gone wrong spectrum and good water = algea good spectrum bad water = algea its either phos, nitrates, or spectrum

thanks for the feedback I will try scrubbing off the rocks.....that will be a treat!!!

GHA needs nutients to feed on. Give it all the light you want. No nutrients - no GHA. You may have a bush here or there, but that is just part of the system.

Find out where your nutients are comming from. I've been down the road. I had to find my nutrient source. Found it in the salt mix I was using.

Hmmm interesting.. idon't know don't feed more than normal only 5 fish in a 55. Also, logic tells me that even if I clean the rocks off there will still be debree left on the bottom and such.. I may have to start over.....urrrrrggg!!!

Turbo snails work great. When my tank was new every rock was covered with that stuff. I put five turbos and in 2 days they cleaned 40 lbs of rock spotless it never came back

Nobody likes to hear this, but algae issues almost always boil down to room for better husbandry. Better skimmer, less feeding, more water changes, replace bulbs on time, run carbon, etc. Trust me, if you can find out what caused this algae bloom, you'll be a much better reefer. Good luck :)

yup, nutrient control is the key . . . anything to decrease nitropen and phos. My freind turned off his lights for a week with good success. I have a larger tanks and feel the use of ozone has helped alot.

Bandsaw is right. Its about the excess nutrients in my opinion.

How often do you do water changes?

I'm just tagging along. I'm going through the same problem. Everything I test is good but the stuff will not go away. I had cyno about a year ago and I added some chemi-clean and it went away in 3 days and never came back. I wish there was a product that would do the same thing with GHA.

JOHNNIE, Please don't get discouraged. I don't know a reefer yet who has not had the pleasure of dealing with an algae outbreak of some kind. I know of some reefers who let the HA grow on the back of their tanks. It's a bit of a compromise, grow on the back and leave my rocks alone.

I am in the middle of the battle myself. Have been for about 3 months. Just two weeks ago, my HA was in deep decline, I figured I had it beat and in 2 months it would all gone. Then suddenly it came back with a vengeance.

The trick is to find out what is fueling the HA. For myself, I am looking at two possible sources as I am seeing a pattern of high and lows with my algae and they are related to either my brand of salt or my RO/DI holding tank is leaching something. I went out and got a TDS meter and tested my RO. It tested at 5 (expected here, the water going in has a TDS beyond the RO Units specs). Over a week’s time, the TDS of the water in the holding tank went up to 40. So either my RO water is becoming contaminated or the plastic tub is leaching something.

I may have some contaminated salt mix. Either way, my HA comes alive with growth when I do a water change.

As ugly as it looks, I am letting mine grow as opposed to picking it out. Any of my rocks that have good coralline growth is unaffected. I figure the more I let it grow, the sooner it will use up the nutrients in the water.

There are other sources that the HA may be drawing from. Your Live Rock may have had a natural build up of fuel. If that is the case, you are going to have to let the HA grow until all that fuel is depleted.

Just stay with it. It is depressing. There are days that I look at mine and just shrug. Especially this past two weeks when I thought I had it beat.

Good house keeping, feed to a minimum (mine get feed only every other day - sometimes every three days) - good skimming - and find those nutrients - and don't give up!

I forgot who the member was but he strongly advocated the process of "cooking" your live rock in order to combat GHA.

do you use ro/di- you should and make sure its had a filter change of late

water changes

what salt mix has extra nutrients in it- that ain't cool!

alphaferret, I'm not sold on the idea yet that my Instant Ocean is the cause. Yet I have read enough bad press in other threads to make me suspeciouis.

I suspect more my RO/DI water tank is to blame. I've switched back to using 16L pails (Food grade pairs - had kanola oil in them) to see if things improve.

As for JOHNNIE, I don't know if he uses RO/DI or not. I do. Last filter changes just before Christmas.

I went to a local reef club meeting today and a lady there checked the TDS of the water I had been getting from the Kroger RO machine. It measured 15. I got 2 differant answers as to if this was ok or not.

The buckets sometimes will leach stuff back into the water. Even the Rubbermaid Brute trashcans will leach a little back into the water. I use the 5g lfs water containers to hold the ro/do water for topoff and for waterchanges. It always test at zero.

Sometimes an open water container food grade or the simple hd buckets will start leaching stuff back into the water. Put those lids on to keep stuff from getting into the water.

What is normal? What kind of fishes are in the tank? How big? How much LR? Did you cure the rock in the tank with the sandbed in place? Are you using RO/DI water or tap?

I see somebody proposed "cooking" the rock, but b4 you even consider going that route you need to figure out why the algae outbreak started. I do believe "cooking" is an option and that it works great, but not b4 you find out why you have an outbreak in the tank. Fix the root of the problem first.

im dealing with this problem as well in my 120 fowlr.i got serious about getting my phosphates and nitrates down to a decent level.and took one rock out at a time ,in a 5 gallon bucket of my tank water,and used a good size brush and scrubbed them.then rinsed them off in some freshwater and put them back in the tank.
its been around 3 days now and i havent seen any yet.not to mention my rocks look sparkling clean.its about 180 lbs of rock.it took me awhile but well worth the effort.now im not saying that it wont come back,nothing surprises me in this hobby anymore.good luck.

You would start over rather than turn your lights out. I think it would be less work and cost to just turn your lights out and do some water changes as the algae dies.

Thanks a ton for all the advice guys.

Lets see well to start the tank has been running for over two years old. I only use RO from my local walmart at 29 cents a gallon can't beat that. I use 1 400 W MH 20k..its about 7 months old...have another 400w MH just not in use right new brand new...so all the rock 75-100pounds is over to one side top ftry and control it better plus thats where the light is...

I do have a turboflotor skimmer that is about shot( It produces very little skimmate...even when I clean it it'll work fine for a week then suck again!!maybe I need a more powerful pump on it...), need to upgrade or go backpack...In the process of hooking up my fuge/sump. I have read that this would help keep the nutrients down in the fuge area as I will be going reverse lighting. (I got it from a guy on the board..about time I used it...)

I did at one point turn the lights out for a week and almost ...97% of it was gone....., but it came back a few weeks later, not really sure what I did different but feed normal amounts of flake food to the fish...HOWEVER I DID ADD SALT THE GOOD OCEANIC KIND) other than that.....Oh I have an old BIO wheel i simply use for more (circulation and carbon)...that may be a problem too...getting rid of that, just hasn't cuase me a problem until now.

Sorry for babbling just thinking outloud....

Anyone have a fuge going ...does it reallly help...I will work on mine in the next week or so...Just need to get a better skimmer first....as it won't fit in my sump.......Oh and I do have an anemome not sure if he can take it with the lights out for a week..

thanks for any more help.:cool:
